Frequency comb ptychoscopy [PDF]

Nature Communications, 2021
Multiheterodyne techniques using frequency combs—radiation sources whose lines are perfectly evenly-spaced—have revolutionized science. By beating sources with the many lines of a comb, their spectra are recovered.

Dynamics of the Frequency Shifts in Semiconductor Lasers under the Injection of a Frequency Comb

Photonics, 2022
We have numerically investigated the dynamics of frequency shifts in semiconductor lasers under the injection of a frequency comb. We have studied the effect of comb spacing on the locking bandwidth.

Frequency pushing and pulling in semiconductor lasers subject to optical frequency comb injection

Results in Engineering
We theoretically investigate the frequency shift of a free-running semiconductor laser when optically injected by an optical frequency comb. By numerical integration of the laser rate equations, we have identified two types of frequency shifts, frequency

Optical Frequency Comb Generation based on Erbium Fiber Lasers

Nanophotonics, 2016
Optical frequency combs have revolutionized optical frequency metrology and are being actively investigated in a number of applications outside of pure optical frequency metrology. For reasons of cost, robustness, performance, and flexibility, the erbium

Pump-threshold-free frequency comb via cavity Floquet engineering [PDF]

Nature Communications
Frequency combs have revolutionized communication, metrology, and spectroscopy. Considerable efforts have been devoted to developing integrated combs, primarily leveraging Pockels or Kerr nonlinearities. Here, we demonstrate an alternative frequency comb

Metrology of frequency comb sources: assessing the coherence, from multimode to mode-locked operation [PDF]

Nanophotonics
Since the beginning of this millennium, frequency comb generators have reshaped frequency metrology and related areas. After more than two decades since their first realization, several other ways to generate frequency combs, in any spectral region, have
